What is aatcc 127?
AATCC 127 Hydrostatic Pressure Test measures the resistance of a fabric to the penetration of water under hydrostatic pressure. It is applicable to all types of fabrics, including those treated with a water resistant or water repellent finish.
What is Aatcc test method?
The AATCC 100 test method method is designed to quantitatively test the ability of fabrics and textiles to inhibit the growth of microorganisms or kill them, over a 24 hour period of contact.
How do you measure water resistant material?
The water repellency of fabric is measured in pounds per square inch (psi). Water resistancy of a fabric is determined by a water pressure test. The higher the psi, means the more water the fabric can repel before having water pass through the fabric and getting the wearer wet.
What is the difference between AATCC 100 and AATCC 147?
What is the difference between AATCC 100 and AATCC 147? A： AATCC 100 is a quantitative method to evaluate the degree of antibacterial activity. AATCC is a qualitative method to determine antibacterial activity of diffusable antimicrobial agents on treated textile materials.
What is the resistance of pure water?
As previously mentioned, a specific resistance 18.2 MΩ × cm (million ohms) at 25°C is considered to be absolute pure water. This only accounts for the dissolved ionic impurities commonly found in water. Organic materials found in water cannot be directly detected by resistivity | conductivity.
What is iso16604?
ISO 16604:2004 describes a laboratory test method for measuring the resistance of materials used in protective clothing to penetration by blood-borne pathogens. This test method uses a surrogate microbe under conditions of continuous liquid contact. This test method involves a sensitive assay procedure.
What is ASTM F2101?
ASTM F2101 – 19. ASTM International (ASTM) Title. “Standard Test Method for Evaluating the Bacterial Filtration Efficiency (BFE) of Medical Face Mask Materials, Using a Biological Aerosol of Staphylococcus aureus”
What is ASTM f1671?
This test method is used to measure the resistance of materials used in protective clothing to penetration by blood-borne pathogens using a surrogate microbe under conditions of continuous liquid contact. Protective clothing material pass/fail determinations are based on the detection of viral penetration.
